To all whom it may concern:

Be it known that I, Hnoo Baronet, a citi zen of the United States, residing at Chicago, in the county of Cook and State of ful Improvements in Cutting or Slitting Machines, of which the following is a de-, scription.

My invention relates to cutting mechanisms suitable for cutting belts or other heavy fabrics, such as automobile tires and the like.-

The object'of my invention is to provide I a strong, simple, durable and convenient de- Vice of the kind described which may be employed upon almost any material and is especially'serviceable for removing the clenchers from automobile tires. To this end my invention. consists in the novel construction, arrangement and combination -iof parts herein shown and described a'nd'rnore particularly pointed-out in the claims.- I a In the accompanying drawings wherein Figure 1 is a Fig. 2 is an end elevation of the same. Fig. dis a fragmentary detail of the movable bearing. of

Fig.4 is a similar view showing the cutter in operative'position: Fig. 5 v is a plan view of my device with an automobile tire in position to be out.

In the form'shown my device consists of like or corresponding parts:

' 85 suitable supporting .legs or brackets 1l with a table or thereon and a pair frame 2. rigidly mounted of yokes or guides 3-4 -mounted at opposite ends of the frame 2 respectively. As shown the yokes 3 and 4:. are similar and comprise a pair of upright parallel guides connected at their top and suitably spaced from eachother to receive a. pair of bearings in each yoke. The bearings 5 and 6 are rigidly secured m in the respective yokes and adapted tosupport a shaft 7 in position. v The bearing 8 in the yoke l is pivotally mounted in position by means suitable means rigidly secured in the yoke 50 and pivotally engaging the bearing 8. at approximately its-center. The bearing 10 in the yoke 3 is arranged to move vertically and at the same time adjust itself to accommodate a shaft 10 the opposite end of which the bearing 8'.'- Any suitable means may be provided to control the Specification of Letters Patent.

position of the bearing 10. As shown a sprmg 12 is positioned between the bearings 5 andlO adapted to hold the bearing 10 at the upper limit of its movement while a setscrew 14 or other convenient means is arranged in the yoke to limit the upward movement of the bearing and to adjust the same if desired. In the 'formshown the po- 'sition of the bearing 10 is also contro by a foot treadle or lever 16 pivotally attached to the frame 1 as at 17 and connected to the bearing by a forked rod the forked end of which is attached to opposite sides of the bearing and extends downward to the treadle. When the treadle is depressed the bearing 10 is moved downward toward the bearing 5.

In the form shown my, improved cutting mechanismis mounted upon the'ends of the shafts 7 and 11, and comprises a pair of disks or rollers 18 and 19 rigidly attached to the shaft 7 beyond the housing 5. The adjacent faces of these disks are preferably fiat, substantially parallel, and suitably spaced from eachother to permit the cutter tween them and coiiperate with the edges of the rollers to operate as a shear. Where my device is to be employed upon automobile tires the outer end of the roller-19 is rounded as shown in Figs. 1 and 4 to correspond in a. measure with the usual form-of the in-. terior of an automobile tire. The cutter 20 is merely a circular disk suitably formed at its edges to cotiperate and 19- and rigidly secured to the shaft 11 by collars 21 and 22 or other suitable means with a nut23 or other convenient clamping means for forcing the collars together upon the disk. The collar 21 is preferably recessed adjacent the cutter 20 to afford sufficient space for the clencher of an automobile the collar 21 and roller 18. The collar 22 however is substantially cylindri'cal its outer face being arranged to cooperate with the periphery of'the roller 19 to eng them'to feed the material to the cutter.

Any suitable means may be provided for rotating the shafts 7 and 11. As shown a pair of gears 25 and 26 are rigidly secured to the shafts 7 and llfrespectively of suit able size to-rotativelyconnect the shaft 11 to the shaft-f7; A gear 27is also rigidly secured to the shaft 7' and extends through a suitable opening the plate and meshes.

In the preferred construction also suitable means are provided for partially support.

ing the material being operated upon. As shown, a pair of Substantially horizontal rollers 36 and 37 are mounted in suitable brackets upon the frame in position to par tially support the automobile tire or other material to be cut in the most convenient position. As shown, suitable means are alsoprovided for guiding the material to the cutters, for this purpose an arm 88 is shown pivotally mounted upon the plate 2 as at 39, and provided with a suitable vertical roller 40 positioned to engage the edge of the tire to direct it to the cutters. Obviously if desired the arm 38 may be moved to any desired posit-ion and clamped against accidental displacement thus providing an accurate adjustable guide for the device.

In operation the tire is positioned upon the roller 19 as shown in Figs. 1-4 and 5 the footdever 16 is then depressed forcing the cutter 520 through the fabric, the edge of the cutter being preferably sharpened to facilitate this operation. As soon as a collar 22 engages the tire and presses it against the roller 19 with suiiicicnt force the tire will be moved or fed along producing a smooth even out. Obviously for cutting comparatively thin fabric or metal it is important to sharpen the cutter 20 so as to ed"- operate with the roller 19 to produce the best possible shearing out. For thicker fabric however, While the shearing action. is important to produce a satisfactorily clean out the form of the knife may be considerably varied Without serious objection.

Having thus described my improvement it is obvious that various immaterial modifications may be made in my device Without departing from the spirit of my invention; hence I do not Wish to be understood as limiting' myself to the exact form or construe tion shown.

W I claim as new and desire to secure by Letters Patent is:

l. 11in a device of the kind described, a pair of cutting members adapted to cooperate as a shear and means for normally maintaining one of said members out of operative position, in combination With means at each of said members adapted to co'cvperate to feed the material to the cutters, and means for manually maintaining said first men tioned member and its feeding means in operative position.

; 2. In a device of the kind described, pair of cutting members adapted to cooperate as a shear, means for normally maintaining one of said cutters out of operative position and mechanismfor manually controlling the distance bet-ween said cutters, in combination with means upon said members adapt ed to coiiperate to feed the material to the cutters, and means for directing said mate rial during the cutting operation.

3. In a device of the kind described, a pair of cutting members adapted to cooperate as a shear, one of which is laterally movable, means for yieldingly holding said laterally movable cutter out of cutting position in combination With means at each cutter adapted to coiperate to feed the material to the cutters and mechanism for manually maintaining said laterally movable cutter and its feeding means in operative position.

4. In a device of the kind described, a pair of circular rotary cutting members adapted to coiiperate as a shear, one of Which is laterally movable, resilient means for normally maintaining said laterally movable member out of cutting position, in combination with means for manually controlling the distance between said cutters and means upon said members adapted to cciiperate to feed the material to the cutters.

5. In a device of the kind described, a pair of circular rotary cutting members adapted to coiiperate as a" shear, one of which is laterally movable, means for normally maintaining said laterally movable member out of cutting position and means/for manually controllingthe, distance between said cutters, in combination with means mounte'd concentrically ith and rigidly attached. to said members adapted to cooperate only when said cutters are in operative position to feed the material to the cutters.

in testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses. I
